The LPS33HW from STMicroelectronics is an absolute pressure sensor engineered for reliability in damp or chemically aggressive environments. Its sensing core is housed within a ceramic LGA package and encapsulated with a specialized waterproof gel, providing robust protection against water ingress mixed with chlorine, solvents, and detergents. This design ensures long-term stability and accurate readings even under harsh conditions.
The module delivers calibrated pressure data with a high-resolution 24-bit ADC and includes integrated 16-bit temperature sensing for compensation, maintaining accuracy across its full operating temperature range. It features an adjustable output data rate and an integrated low-pass filter to minimize signal noise. The breakout board from Adafruit incorporates necessary support circuitry, including voltage regulation and logic level translation, making it directly compatible with both 3.3V and 5V development platforms.
